<refnamediv id="fract">
Fractional value in <varname>x</varname>.

<!-- ================================ DESCRIPTION -->
<refsect1 id="description"><title>Description</title>
<para>Returns <citerefentry><refentrytitle>fmin</refentrytitle></citerefentry>(<varname> x</varname> - <citerefentry><refentrytitle>floor</refentrytitle></citerefentry>(<varname>x</varname>), 0x1.fffffep-1f ).
<citerefentry><refentrytitle>floor</refentrytitle></citerefentry>(<varname>x</varname>) is returned in <varname>iptr</varname>.
<!-- ================================ NOTES -->
<refsect1 id="notes"><title>Notes</title>
The min() operator is there to prevent <function>fract</function>(-small ) from returning 1.0. It returns the largest positive floating-point number less than 1.0.</para>
The vector versions of the math functions operate component-wise. The description is per-component.
The built-in math functions are not affected by the prevailing rounding mode in the calling
environment, and always return the same value as they would if called with the round to nearest
even rounding mode.
This built-in math function takes scalar or vector arguments. The generic type name <type>gentype</type> is used to indicate that the function can take <type>float</type>, <type>float2</type>, <type>float4</type>, <type>float8</type>, or <type>float16</type> as the type for the arguments. For any specific
use of these function, the actual type has to be the same for all arguments and the return type.
If extended with <citerefentry><refentrytitle>cl_khr_fp64</refentrytitle></citerefentry>, generic type name <type>gentype</type> may indicate <type>double</type> and <type>double{2|4|8|16}</type> as arguments and return values. If extended with <citerefentry><refentrytitle>cl_khr_fp16</refentrytitle></citerefentry>, generic type name <type>gentype</type> may indicate <type>half</type> and <type>half{2|4|8|16}</type> as arguments and return values.
